Effectiveness of Hand-Out Based on a Scientific Approach in Improving the Numeracy Literacy Skill of Class V Elementary School Students

Numeracy literacy skill need to be equipped by students to solve mathematical problem. To achieve this goal, teaching materials such as hand-out based on a scientific approach are needed in learning mathematics. Therefore, this research aims to develop students' numeracy literacy skill by using hand-out based on a scientific approach. This research involved 24 elementary school fifth grade students. The research design used in this study was a one group pre-test post-test design. Data was collected through a numeracy literacy skill test and analyzed using descriptive statistics taking into account aspects of the n-gain index calculation. The results showed that the pre-test average score of students' numeracy literacy skill is 66.33 in the medium category. While the average post-test score of 88 students is in the very high category. The results of calculating the average n-gain index in individual, group and field trials each obtained a value of 0.7 or in the medium category. This indicates that there is an increase in the score of students' numeracy literacy skill. Thus, there is an increase in the average value of students' literacy skill before using and after using scientific approach-based hand-out. Thus, it can be concluded that using hand-out based on a scientific approach is effective in improving students' numeracy literacy skill.
